United States Patent US. Cl. 260--94.3 30 Claims ABSTRACT OF THE DISCLOSURE A catalyst system and method for polymerizing unsaturated monomers wherein the catalyst comprises certain compounds containing vanadium-oxygen-phosphorus in combination with certain aluminum compounds and silicon compounds.

The present invention provides a polymerization method and catalyst system comprising an aluminum halide, a silane and a vanadium-oxygen-phosphorus component. The catalyst composition is capable of polymerizing and copolymerizing ethylenically unsaturated monomers such as olefins, a-Olefins, diolefins, vinyl monomers and the like.

The preparation and use of these vanadium-oxygenphosphorus compounds in conjunction with certain organoaluminum compounds as cocatalysts is disclosed and claimed in commonly assigned, copending application Ser. No. 465,210, filed June 18, 1965 and in copending application, Ser. No. 500,329, filed Oct. 21, 1965, which is a continuation-in-part of said Ser. No. 465,210. In these applications the primary catalyst component is produced by the reaction of a vanadium oxide with an organic phosphorus oxy compound. The cocatalyst is usually an organoaluminum compound.

In the later filed application the primary VOP catalyst component preparation reaction is specifically disclosed to be eflected by including a polar additive, in the reaction mixture in addition to the vanadium oxide and the organic phosphorus oxy compound. The presence of the polar additive during this reaction results in the production of an active catalyst in a much shorter time at the same reaction temperature than when the polar additive is not present. Additionally, a much more active catalyst component can be produced in a given reaction time than is the case when no such polar additive is used.

The polymerization processes and catalysts of the invention are adapted for preparation of a wide range of polymers from the corresponding olefinically unsaturated monomers. This catalyst and method of the present invention is applicable to the preparation of both homopolymers and copolymers, such as for instance: (1) vinyl resins formed by the polymerization of vinyl halides or by the copolymerization of vinyl halides (e.g. vinyl chloride) with unsaturated polymerizable compounds, e.g., vinyl esters, a,B-l11'1S3.t111'at6d acid, a,B-unsaturated esters, OLE-unsaturated ketone's, u,B-unsaturated aldehydes and unsaturated hydrocarbons such as butadienes (e.g. 1,3-butadiene), styrenes (e.g. styrene) and olefins such as ethylene, propylene or l-butene; (2) poly-a-olefins such as polyethylene polypropylene, polybutylene, polyisoprene and poly(l,3-bu-tadiene) including copolymers of a-olefins with other monoand di-olefins; (3) polystyrene, and copolymers of styrene with monomeric compounds such as acrylonitrile and butadiene; (4) acrylic resins as exemplified by the polymers of methyl acrylate, methacrylonitrile, acrylamide, methylol acrylamide, acryloni- 3,476,732 Patented Nov. 4, 1969 trile, and copolymers of these with styrene, vinyl pyridines, etc.; (5) neoprene; and (6) unsaturated polyesters. This list is not meant to be limiting or exhaustive but merely to illustrate the wide range of polymeric materials which can be obtained by the present invention. Of special interest are olefinically unsaturated hydrocarbons having at least one carbon to carbon double bond, especially those having a terminal double bond.

The process and catalyst composition of this invention are particularly suited to the preparation of polymers and copolymers from alpha-olefins, styrenes, diolefins and vinyl halides such as ethylene, propylene, styrene, 1,3- butadiene, and vinyl chloride.

The primary catalyst component of the catalyst combination of this invention is produced by the reaction of a vanadium oxide of the formula wherein nis an integer from 3 to 5, with an organic phosphorus oxy compound. Usual organic phosphorus oxy compounds have the formula wherein R R and R are independently members selected from hydrogen, hydroxyl, alkyl having from 1 to 8 carbon atoms, alkoxy having from 1 to 8 carbon atoms and aryl, wherein at least one such selected member is an organic group.

Especially useful phosphorus compounds of the above formula are alkyl and aryl phosphonic acids.

The primary catalyst system can be prepared by the reaction of the vanadium oxide with the organic phosphorus oxy compound in a weight ratio of from about 1:6 to about 6:1, more usually from about 1:4 to about 4:1. An especially useful primary catalyst component is produced by the reaction of vanadium pentoxide with phenyl phosphonic acid.

In one embodiment of the present invention, the reaction between the vanadium oxide and the organic phosphorus oxy compound referred to above is carried out in the presence of a polar additive, which is, for example, water, an alcohol, an aldehyde, an ether, a 'ketone, an organic amine, an organic acid, an inorganic acid, a dioxane, a furan, or a pyridine. Examples of specific polar additives are water, methanol, ethanol, acetone, 2-propanol, n-butyl alcohol, tertiary butyl alcohol, methyl ethyl ketone, dioxane, tetrahydrofuran, diethylamine, triethylamine, formic acid, acetic acid and benzene sulfonic acid.

Preparation of the reaction product of the vanadium oxide and the phosphorus compound (hereinafter called VOP) in the presence of the polar additive produces an active catalyst component in a much shorter time at the same reaction temperature than when the polar additive is not present. Further, a much more active catalyst can be produced in a given reaction time than in the absence of the polar additive.

The primary catalyst component (VOP) is used in conjunction with a cocatalyst which is represented by a hydrocarbyl silane having the formula wherein n is from 1 to 3 and R is a hydrocarbyl group containing from 1 to 10 carbon atoms, Z is a member selected from the group consisting of H and an alkenyl group having at least 3 carbon atoms; and a compound 3 where X is a halogen with an atomic number from 17 to 53, G is X or a radical -OR where R is as before defined.

The VOP component can be produced by the reaction of the vanadium oxide with the organic phosphorus oxy compoud at a temperature of from about 80 to about 200 C. for a period of time of from about 1 to about 24 hours in the presence of a solvent such as an aliphatic or aromatic hydrocarbon. Sufiicient solvent to slurry the product primary catalyst is usually present. A particularly useful range of operating conditions for the preparation of the primary catalyst is from about 50 to about 100 C. for a period of time of from about 5 to about 24 hours. An especially useful primary catalyst component as described above is produced by the reaction of 1 part vanadium pentoxide with 4 parts of phenyl phosphonic acid in the presence of benzene at a temperature of 80 C. for 24 hours.

It is to be noted that the primary catalyst component can be prepared by directly reacting the vanadium oxide with the organic phosphorus oxy compound in the absence of a solvent. This hot melt reaction technique can be carried out at a temperature of from about 160 to about 200 C. at atmospheric pressure for a period of time of from about 1 minute to about 1 hour but higher or lower temperatures can be used. A usual set of reaction conditions for this reaction sequence is 180 C. at atmospheric pressure for 5 minutes.

When polar additives are present in the VOP preparation reaction, they are usually present in an amount not more than about 6 parts by weight per part of the vanadium oxide. An especially efiicacious polar reaction system to produce an exceptionally active catalyst component in a short time, is the contacting of V with 3 to 5 parts by weight of phenyl phosphonic acid and from about 0.05 to 3 parts by weight of a C to C alkanol for each part by weight of V 0 Reaction temperatures are not critical but, of course, affect the rate of reaction. Temperatures much below 80 C. are applicable, and temperatures as low as 40 C. can give reasonable reaction rates. Also, temperatures well above 200 C. can be employed in given instances but care must be taken not to decompose reactants, as will be understood. Usual temperatures employed are in the range from 40 to 250 C. It is difiicult to specify any precise time of reaction, but the necessary time can be determined in a routine manner by testing in a polymerization recipe the catalytic activity of a series of catalytic components made using various reaction times. Generally, we have found a time of 1 to 4 hours to sufiice when using reaction temperatures of 50 to 100 C., while much shorter times on the order of 1 minute or a few minutes are effective at the higher temperatures. We now prefer to effect the contacting and reaction in the presence of an inert liquid diluent or solvent, such as an aromatic, aliphatic or cycloaliphatic hydrocarbon. After reaction, the catalyst component solid can be separated from the diluent by evaporation. When benzene is the solvent the temperature of evaporation is usually 35 to 85 C., lower temperatures being used with application of vacuum. Any excess unreacted polar additive remaining after the reaction is essentially complete, is removed by the drying procedure if the additive is a volatile one. If the additive is not removed by the drying procedure, small amounts can remain in the solid catalyst component. It should be remembered, however, that it is desirable to remove any appreciable amounts of the polar additive When such additive would be reactive with the cocatalyst. Such removal is simply accomplished by washing the solid reaction product with a solvent for the polar additive, and then drying the solid product. Sufficient diluent or solvent to slurry the product primary catalyst component produced is usually present.

The aluminum silane complex can be prepared in and isolated from, hydrocarbon solvents such as heptane,

aromatic solvents such as benzene and other inert solvents.

The complex can also be prepared in situ such as by adding the aluminum halide and the silane compound to an inert solvent reacting then for a period of time at an elevated temperature and then adding the VOP catalyst and monomer to be polymerized.

In the silicon compounds of the formula R SiZ as before defined, R can be, for instance, an alkyl, alkenyl, aryl, aralkyl, cycloalkyl or alkaryl group, such as ethyl, n-propyl, iso-propyl, allyl, propenyl, phenyl and benzyl. These compounds are named as derivatives of silane, SiH As disclosed above, Z is a member selected from the group consisting of H and an alkenyl group having at least 3 carbon atoms, such as allyl. Specific examples are diphenyl silane, triphenyl silane, di-l-naphthyl silane, phenyl silane, triethylsilane, triisopropyl silane, tri- (n-propyl)silane, diphenylmethylsilane', dibenzylmethylsilane, triallylsilane, tri(n-hexyl)silane, tribenzylsilane, trimethylsilane, tributylsilane, allyltrimethylsilane, allyltriethylsilane, diallyldimethylsilane, vinylallylmethylethylsilane, triallylethylsilane, tetraallylsilane, di(3-butenyl)dimethylsilane, 4-pentenyltrimethylsilane, tri(5-hexenyl) methylsilane and (2,4,6-trimethylphenyl)triallylsilane.

Especially preferred are the compounds R SiH Where each R is an aliphatic hydrocarbon group having 1 to 6 carbon atoms.

Examples of the compounds of the formula are AlCl AlBr AlI ethoxyaluminum dichloride, phenoxyaluminum dibromide, dimethoxyaluminum chloride, butoxyaluminum dichloride and phenylethoxyaluminum chloride, AlCl and AlBr are especially useful.

It is convenient to effect the polymerization of the monomers while the catalyst components are dispersed (dissolved, or suspended as a particulate solid) in an inert liquified diluent. However, it is not necessary, in order to obtain polymerization of the monomer to a polymer, to employ a diluent or solvent. The diluents that can be used in the process include, for example, aliphatic hydrocarbons, cycloaliphatic hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons. Examples of suitable inert diluents that can be employed include organic solvents such as benzene, toluene, n-heptane, cyclohexane and carbon tetrachloride. The particular diluent is not critical so long as it is not reactive with the components of the catalyst.

It is a feature of this invention that high pressures are not necessary, although they can be employed if desired. It is, however, an advantage that pressures from subatmospheric to less than 300 p.s.i.g. are perfectly satisfactory.

While the catalyst composition is described herein as a mixture of the three components, the composition herein and in the claims covers whatever reaction product is formed, if any, when such components are admixed.

The process of the invention is especially advantageous when ethylene or 1,3-butadiene is the monomer. The polymers can be employed for the many known uses of plastic and rubbery high polymers. For instance, the polymers are thermoplastic and can be pressure molded to form articles such as bowls, tumblers, etc. The polymers of conjugated dienes can also be molded and vulcanized with conventional rubber vulcanization accelerators and sulfur to form tough molded articles. The polymers can also be extruded to form tubing for carrying water in laboratories and homes.

The following examples of the invention are illustrative only and are not to be considered as limiting the scope of the invention in any manner.
